VFD (Variable Frequency Drive) Cable Overview
1. Voltage Ratings & Applications
  • 300/500V: Low-voltage control circuits, sensors, and PLC interfaces.
  • 600/1000V: Standard industrial motor power supply.
  • 2000V (2kV): High-performance use to manage extreme voltage spikes.
  • 3.3kV+: Heavy-duty applications like mining, oil & gas, and large-scale industry.
2. Key Construction Features
  • Flexible Conductors: Stranded copper for easier installation and vibration resistance.
  • High-Grade Insulation (XLPE/EPR): Manages heat and prevents electrical breakdown.
  • Double Shielding (EMC Grade): Foil and braid combinations to block electrical noise.
  • Robust Sheathing: Oil-resistant and Flame Retardant (LSZH) options for harsh environments.
  • Grounding Design: Symmetrical ground wires to reduce "stray" currents and protect motor bearings.

*Selection Tips:      

  • Long runs/high interference: Use double shielding (aluminum foil + copper braid) and ground shield at both ends

  • Tight spaces: Choose PUR outer jacket cables for superior flexibility

  • Fire-sensitive areas: Use LSZH jacketed cables for smoke-free installations

  • Combined power + signal: Use hybrid VFD cables with integrated feedback/control pairs


   


   

CHARACTORISTICS OF Summary

1. Material Comparison: Which one do you need?

MaterialBest For...Key Performance
XLPEHeavy Duty & HeatHandles high temperatures (up to 90°C) and short circuits (250°C). Excellent strength.
PVCGeneral Use & Cost
EPR (Rubber)Extreme WeatherWorks in freezing cold (-40°C) or high heat (+120°C). Great against UV/Sunlight.
PURRough ConditionsSuper tough! Resists oil, tearing, and abrasion. Perfect for moving machinery.


2. Quick Selection Checklist

  • Need high heat resistance? Choose XLPE or EPR .
  • Need to resist oil and rubbing? Choose PUR .
  • Budget-friendly indoor project? Choose PVC .
  • Outdoor/Ozone exposure? Choose EPR .
3. Installation Rule: The "Bending Radius"
Cables can damage their internal wires if bent too sharply. Use the "D" Rule (where D is the outer diameter of the cable) to ensure a safe installation:
  • Standard Installation:
    • Single Core: Bend no tighter than 20x the cable diameter.
    • Multi-Core: Bend no tighter than 15x the cable diameter.
  • Near Terminal Boxes: You can bend slightly tighter (eg, 12D or 10D ) if using a formed guide to support the cable.
    • Note: Armored cables (with metal protection) can handle tighter bends than unarmored ones during installation.
